Genes affected

ZHX3 (HGNC:15935): (zinc fingers and homeoboxes 3) This gene encodes a member of the zinc fingers and homeoboxes (ZHX) gene family. The encoded protein contains two C2H2-type zinc fingers and five homeodomains and forms a dimer with itself or with zinc fingers and homeoboxes family member 1. In the nucleus, the dimerized protein interacts with the A subunit of the ubiquitous transcription factor nuclear factor-Y and may function as a transcriptional repressor.

This variant has not been reported in the literature in individuals affected with ZHX3-related conditions. This variant is present in population databases (rs748783597, gnomAD 0.2%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 919 of the ZHX3 protein (p.Thr919Ala). ClinVar contains an entry for this variant (Variation ID: 1402056). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. -
